3 quarter twist Möbius strip (color)

This variation of the Möbius loop has a three quarter twist instead of a half-twist, leading to a self-intersecting surface.

The irregular hole pattern has been calculated by simulating a Gray-Scott reaction diffusion process on the surface.
The algorithm has been modified so that at the sites of self-intersection, the different parts of the surface do not touch but instead weave through each other's holes.
